Applicationled February 2, 1927, SerialNo. 165,437, and in Cuba January 17, 1927.

This invention refers to refrigerators7 and has for its main object,.the substitutlon yof the coil, which is used in devices of this kind,

for a chamber wherein the water is forced.y

to circulate exactly in an analogous relation to the circulation in a coil, but with the very important advantage, that said chamber 1s provided with a dismountable cover or bot-` circulation chamber, may be veffected by anyone with little experience, and at will; said chamber may be galvanized or enamelled innerly and outerly.

Another advantage of this invention, 1s that the refrigerating surface is considerably increased, with respect to the refrigerating surface of the coil in use, which is never in complete contact with the ice and besides,y

has dead spaces, that is to say, those spaces caused by the bend in the pipe, and causing a considerable waste of ice, the refrigerating power of which is not absorbed by the coil.

Another advantage of the invention is that the chamber of circulation, has a capacity for a greater volume of water than that which may be contained in a tubular coil.

The invention is shown in the attached drawings and described in the course of these specifications, wherein the same characters of reference designate the same parts in the different views.

Fig. 1, is a side elevation in detail of the improvement, object of the present invention.

Fig. 2, is an upper plan view of same.

Fig. 3, is a plan view of the lower part of said improvement.

Fig. 4, is a longitudinal vertical section according to lines 4 4 of Fig. 2.

Fig. 5, is a vertical transversal section according to lines 5 5 in Fig. 2.

Fig. 6, is a horizontal section according to lines 6 6 of Fig. 1.

Fig. 7, represents a section equivalent to that shown according to lines 5 5 of Fig. 2, in a modified form of the invention.

F ig. 8, shows a section equivalent to that 4 4 of Fig. 2in

in sameis designated by l, a' metallic caseofrectangular form, and placed in an inverted position, that is, with its bottom 1" up, and lits open part down. v Said case has its interior divided in a plurality of passages 2, separated incompletely the one from the other by partitions 3 which are cut off on` their ends in alternate relation, to each other, as clearly shown in Fig. 6, so that all are intercommunicated. i

Said case 1 is supported and closed by a rectangular plate 4 by the intermediation of a sheetof material for hydraulic joint 5, being secured with respect to the plate 4 by set screws 6, screwed on ears-1 `projecting from the ears of the case l, passingl through 'coinciding bores opened in ears 4 projecting from the plate or cover 4, and having screwed on the projecting ends of said screws 6, the nuts 6. f

This case 1 has on one of its sides recesses 1 in which is opened threaded bores 7 and 8, the liquid inlet pipe 9 being screwed in the bore 7 and the outlet pipe 10 in the bore 8. y

The plate 4 is supported by legs 1l, with insulator caps 12.

Upon the upper part 1 of the case 1 are placed the blocks of ice 13, of course the whole of the arrangement shown being inclosed in a refrigerator cabinet which is not shown.

In this way, the liquid passing through the pipe 9 circulates continuously and zigzaggedly through the passages 2 which are formed between the partitions 3, in the direction indicated by the arrows in Fig. 6, exactly in the same way as the water circulates in the usual'coils` and finally being drawn when desired through the pipe 10.

If case 1 is to berepaired or cleaned, the nuts 6 are unscrewed and the box 1.is raised, leaving the interior of same exposed, making it possible to clean same thoroughly.

It will be noted that as the block of ice 13 rests upon the upper part 1 of the refrigeration and circulation chamber, the area of -contact is greater than that existing in vthe coils now in use, and therefore the refrigeration is more complete; to this may be added lit) the capacity ofthe chamber 1 in which aconsiderable-reserve of cold Wateri may. be kept.

In the Fi ures 7, 8 and 9 is shown a modified form o the invention, showingfthe case a current passage 11k formed by two partitions in circumvolution 15 andy.

1 comprising 16 directed in opposite directions the one from the other, and ending-in the centerof the case, and which passage extends from theJ-in1etl pipe 17; totheoutlet or drawing opening 18 as may be clearly seefnkin Fig. 9.

The liquidl therefore circulates inthe dii rection indieatedlby-fthe: arrows-in saidFig.
